泌阳凹陷深层系低孔低渗低显示级别储层测井评价方法

泌阳凹陷安棚深层系属低孔隙度、低渗透率、复杂岩性、微裂缝发育的岩性圈闭型隐蔽性油气藏，录井油气显示级别低，在常规测井曲线上油气层的响应特征不明显，油气层评价遇到较大困难。通过对测井曲线特征分析并结合核磁共振、成像等测井资料，总结出该地区的测井评价方法，在新井生产和老井复查精细解释中取得满意效果。

Log Evaluation Method for Anpeng Deep Formation in Biyang Depression with Poor Porosity and Low Permeability

Anpong deep strata in Biyang depression is a subtle reservoir with poor porosity, low permeability, complex lithology, micro-fractures and lithologic traps. It is quite difficult to accurately evaluate it since its oil-gas indication is poor, in particular, oil-gas responses on conventional logs are not clear. On the basis of log characteristic analysis and combination with nuclear magnetic imaging logging data, a log evaluation method available for this depression is summarized, from which desirable results are obtained in new wells' production interpretation and old wells' recheck and fine interpretations.
